Abstract

A mouthpiece (1) for a water tapping point, for example a water tap (2) or similar installation, has a row of flow modifying elements (6-12) so arranged as to impart to the outflowing water jet (5) a desired, preferably quietly regulated, non-splashing state of flow. At least one of these flow modifiying elements (7) is made wholely or partly of magnetic material on e.g. a ceramic basis, so that the flow channels of the mouthpiece (1) are automatically kept free of incrustation.

Description

[Detailed description of the invention] Mouthpiece for water faucet The present invention provides for the desired quiet, regulated state in the outflowing water stream, without splashing, during brewing. A water faucet or faucet containing a group of water flow mitigation members arranged to provide a constant flow of water. relates to mouthpieces for water faucets of similar equipment.

This type of mouthpiece can, for example, eject water as a powerful jet into its passage. splashes around the sink, wash bowl, or other objects. For example, a water faucet located in a kitchen washbasin or sink that would be inconvenient if It is widely used for. For this purpose, the mouthpiece is designed to adjust the flow rate during brewing. increases and creates a negative pressure, thereby forcing the atmosphere to fill the air gap around the mouthpiece. It has a specially configured flow path that allows it to be drawn into the water through the water. This air , when mixed with water, this water has its characteristic almost milky effervescent splatter Gives outflow condition. This channel consists of multiple plastic and/or metal Numerous minute channels that extend through water flow mitigation members and are prone to deposits (channels) and gaps, the water faucet in question is more or less inactive. It becomes useless. If this happens, remove the mouthpiece and use it more or less. They must be immersed in solutions containing various toxic chemicals. but However, this process is cumbersome and time-consuming, and Despite all safety measures, water used for direct drinking or cooking Therefore, there is a danger of chemical residue caused by this.

Therefore, it is an object of the present invention to Automatically removes deposits when the mouthpiece itself is in operation. It is an object of the present invention to provide a mouthpiece of the above type that can be held in a free state.

According to the invention, this purpose is to provide the mouthpiece with at least one water flow relief This is achieved by making the entire or part of the member made of magnetic material. be done. This creates a magnetic field within the flow path of the mouthpiece, which The tendency of calcium to precipitate as limestone on surfaces surrounding water From one strong crystal form, "Aragonite", to another crystal form that has lost this ability. in a manner known per se, thereby forming a mouthpiece. automatically keeps itself free of deposits.

According to the present invention, when the water flow mitigation member made of a magnetic material is viewed in the water flow direction, the water flow mitigation member group is This is particularly advantageous when located at the forefront. That way, the entire water flow mitigation section Materials, i.e. plastic and/or metal parts, absorb calcium carbonate in water. After changing the mineral component or its crystal form from "aragonite" to "calcite", its This is because it will come into contact with water.

Furthermore, in an advantageous embodiment of the invention, the water flow mitigation element made of magnetic material is at least one piece having an outer diameter equal to the inner diameter of the mouthpiece and extending transversely thereto; As made of magnetizable ceramic material in the shape of a disc with water flow relaxation channels good.

According to the invention, this disc has a diameter of IO to 30%, preferably 15%, of its outer diameter. one preferably centrally located water flow relaxation channel having a diameter of 25% At the same time, a slope or roundness is created between the center hole of the disk and its flat end surface. the disc is axially separated from adjacent members in the group of water flow mitigation members. be separated. This causes the water to pass through most of the magnetic field, which causes it to become carbonated. The crystalline form of calcium is most preferably converted into "calcite".

In another advantageous embodiment of the invention, the entire group of water flow mitigation elements is furthermore made of magnetic material. It can also be formed as an integral unit made of materials to provide a particularly simple and inexpensive construction. good.

In the following, the present invention will be described in detail with reference to the drawings, with reference to preferred embodiments thereof.

Brief description of the drawing FIG. 1 is a side view of the mouthpiece of the present invention attached to a water faucet.

FIG. 2 is an enlarged exploded view of the mouthpiece shown in FIG.

FIG. 3 is a cross-sectional view of the mouthpiece along its axis.

Figure 1 shows a water faucet 2 with an operating handle 4 mounted on a mounting base 3. The mouthpiece l is shown mounted. The water supply faucet 2 may have an appropriate structure. . In the case shown, the water faucet is open and a jet of water 5 or It's out.

FIG. 2 is an enlarged exploded view of the components of the mouthpiece. The components are In order, the first seal ring 6, the first water flow mitigation member 7, the second seal ring 8, and the second seal ring. 12.

These components 6 to 12 are shown in assembled condition in FIG. Figure 3 shows The combination of these components allows the water to pass through before leaving the mouthpiece 1. This figure shows how to form a flow path that passes through the air. Mouthpiece l is attached to screw 13. It is attached to the water supply faucet 2, and here the sole ring 6 or the mouthpiece is connected. It forms the sole between it and the water faucet.

While passing through the flow path of the mouthpiece, the water first hits the upper side 14 of the first water flow mitigation member 7. and then the top of the second water flow mitigation member 9 through the center hole 15 of the first water flow mitigation member 7. It moves downward to the side 18 and is expanded outward again by the second water flow mitigation member 9, and the It enters several minute notches 20 (FIG. 2). The notch 20 is located above the second water flow mitigation member 9. A second water flow mitigation member 9 and a third water flow mitigation member 10 are provided on the side 18 to prevent water from flowing. The water is directed outside the second water flow mitigation member 9 before flowing downward through the narrow gap 19 between the It acts to distribute it evenly along the circumference. The third water flow mitigation member 10 directs water to the second water flow. Lower downward focusing ring directed onto the spherical surface 22 provided on the relief member 9 Growing face 21. This spherical surface 22 allows the water to flow in a cylindrical shape. The water flows further downward toward the net 23 at an emergency flow rate larger than the original flow rate. It flows and exits the mouthpiece 1 via this net 23.

As is known from Bernoulli's pressure equation for the field of potential flow, The pressure in water is inversely proportional to the square of the water flow rate, so with the above conditions, the water A negative pressure is easily formed in the water flow, and the negative pressure is applied along the periphery of the fourth water flow mitigation member 11. Air can be easily drawn in through a plurality of air gaps 24 (FIG. 2) located at It will be understood. The drawn air rushes into the cylindrical water stream from the side of the water. As a result, the water flow is braked and divided by the air. be done. Thereby, water finally comes out of the mouthpiece l via the net 23. However, in that case the water gives it a milky appearance and the water hits the object. filled with countless microscopic air bubbles that reduce the tendency to scatter when It is a calm and rich jet stream.

The embodiment described above is only one of many structures that provide the desired effect, or The water supply faucet may be completely or partially damaged due to the flow path or deposits occurring relatively early. All embodiments consist of a large number of channels and gaps so fine as to be ineffective. common to When this condition occurs, remove the mouthpiece and , the water tap must be soaked in a chemical solution for several hours before it can be used again. stomach.

This is of course a nuisance, but in addition to this, when the water faucet is used again, Chemicals in drinking or cooking water that have not been completely washed away There is always a risk of chemical residue.

According to the present invention, these problems can be solved by using plastic and/or or one or more water flow mitigation members 6 to 12 made of metal. The solution is to make it from a magnetic material, i.e. a ceramic material that can be magnetized. It will be done. This creates a magnetic field in the flow path as the water passes through the mouthpiece. pass through this magnetic field, and the magnetic field of the parentheses causes the calcium carbonate in the water to This property is derived from "aragonite", which is a crystalline form that easily settles as limescale. It is converted into a crystalline form called "calcite" in a manner known per se.

This allows the mouthpiece to repair itself without the need to use chemicals in this regard. Automatically maintains a deposit-free condition without any damage.

In the embodiment shown in FIGS. 2 and 3, the water flow mitigation member 7 is made of a permanent magnetic material. Therefore, the magnetic field is generated at the entrance of the flow path. Therefore, the water flow mitigation section that follows Even if the material itself is not made of magnetic material, the entire flow path remains free of deposits. It will be done.

In this case, the water flow mitigation member 7 made of magnetic material is provided as a disk with a center hole 15. , the center hole 15 is formed on the inner diameter of the casing 12 from the viewpoint of obtaining a preferable water flow state. A diameter of 10 to 30%, preferably 15 to 25% of the outer diameter of the corresponding circle 117 have. The intermediate portion between the flat end surfaces 14 and 16 of the disk 17 is formed with an appropriate slope. The disk is formed by a surface 17 and is further sealed by a second sealing ring 8. It is spaced apart from the upper side 18 of the water flow mitigation member 9 . Further, the second water flow mitigation member 9 It is also slightly lowered into the third water flow mitigation member 10 to increase the spacing.

In the above structure, when the water supply faucet 2 is opened, water first flows to the upper side 14 of the disc 7. I bump into it. The upper side 4 of the water supply faucet 2 directs the water in a direction substantially perpendicular to the lines of force of the magnetic field. The disk is guided inward toward the center hole 15 of the disk. The center hole 15 of the disk is filled with water. It has a diameter that allows it to pass through the magnetic field concentrated within the center hole with strong turbulence.

The water that has passed through the center hole 15 of the disk flows along the lower side 16 of the disk 7 toward its outer periphery. Then the flow is directed outward again, i.e. in a direction almost perpendicular to the field lines of the magnetic field, as above. It will be done. This structure passes most of the force magnetic field formed around the water or magnetic disk 7. Therefore, it is particularly effective. This favorable effect is due to the fact that individual ice grains pass through the disk 7. During this time, the ice particles are blown away by turbulence which significantly increases the distance they travel. It will be uploaded.

Even better effects can be obtained if any of the other water flow mitigation members are also made of magnetic material. However, the optimum effect is achieved when it is applied to all water flow mitigation elements.

In this case, if these parts were made into an integrated unit, it would also be particularly simple and inexpensive. A structure will be obtained.
